1980年在美国得克萨斯州启动了两个监测系统，以发现登革热病例。全州的医生被要求报告登革热病例(被动监测)，27个为地理和种族高危人群提供服务的门诊设施被要求每周报告登革热病例(主动监测)。参加主动监测的两家诊所每周提交急性期血液样本进行登革热病毒分离。63例由登革热1型感染引起的疾病(发病日期8月2日至11月10)通过病毒分离或血清学测试记录；52例(83%)发生在德克萨斯州-墨西哥边境附近的县。56名患者(89%)是西班牙裔；46名(73%)是女性。27名患者(43%)在患病前没有去过美国以外的地方。由于1980年德克萨斯州公共卫生官员从未发现过临床上明显的登革热暴发，因此，主动监测系统发现了56%的病例，这是自1945年以来美国大陆首次记录登革热传播的主要原因。当登革热感染风险被认为很高时，应考虑在其他墨西哥湾沿岸州使用类似的监测系统。
Two surveillance systems were initiated in Texas [USA] in 1980 to detect cases of dengue fever. Physicians throughout the state were requested to report cases of dengue (passive surveillance), and 27 out-patient facilities serving geographically and ethnically high risk populations were asked to report cases of dengue-like illness weekly (active surveillance). Two clinics participating in active surveillance submitted acute-phase blood specimens weekly for dengue virus isolation. Sixty-three cases of illness due to dengue type 1 infection (dates of onset Aug. 2-Nov. 10) were documented by virus isolation or serologic testing; 52 (83%) occurred in counties adjacent to the Texas-Mexico border. Fifty-six patients (89%) were Hispanic; 46 (73%) were females. Twenty-seven patients (43%) had not traveled outside the USA before becoming ill. Since no clinically apparent outbreak of dengue was ever recognized by public health officials in Texas in 1980, the active surveillance system, which detected 56% of the cases, was largely responsible for this first documentation of dengue transmission in the continental USA since 1945. Use of a similar surveillance system in other Gulf Coast states should be considered when the risk of introduction of dengue is considered high.
